A Database of Low‐Temperature Thermochronology in East Asia

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Spatial distribution of low‐temperature thermochronology samples in East Asia. ABSTRACT The low closure temperature of the dating system in low‐temperature thermochronology allows shallow crustal movements to be recorded. In recent decades, this approach has been used extensively in studies of orogenic belt exhumation, sedimentary basin evolution, and ...

Alteration Alteration, Mineralization and Geochemistry of Metamorphic Rocks Hosted Hydrothermal Gold Deposit at Rumbia Mountains, Bombana Regency, Southeast Sulawesi, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2019
In Indonesia, gold is commonly mined from porphyry, epithermal and skarn type deposits that are commonly found in volcanic/magmatic belts. However, were recently numerous gold prospects discovered in association with metamorphic rocks.

Holocene Normal Faulting in the Southern Rocky Mountain Trench; Orogenic Collapse Modulated by Glacial Unloading?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Southern Rocky Mountain Trench (SRMT) is a conspicuous valley in the eastern Canadian Cordillera. It lies above a sharp change in lithospheric strength and thickness and is occupied by a normal fault thought to have last been active in the Eocene.

New orogenic type gold occurrences in the Uyanga ore knot (Central Mongolia) [PDF]

E3S Web of Conferences, 2019
The Khangay-Khentey belt is located in central Mongolia (Central Asian Orogenic Belt). The Uyanga ore knot district of the Khangay metallogenic zone are hosted by the lower-middle Devonian volcanogenic-sedimentary Erdenetsogt formation. The new Burgetei,

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone

Terra Nova, Volume 38, Issue 2, Page 106-115, April 2026.
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Characterization of ore-forming systems - advances and challenges [PDF]

, 2018
Economically viable concentrations of mineral resources are uncommon among the predominantly silicate-dominated rocks in Earth's crust. Most ore deposits that were mined in the past or are currently being extracted were found at or near Earth's surface ...

Geological characteristics of the Daduhe gold belt, western Sichuan, China: Implications for exploration

Open Geosciences
Geological characteristics, genetic model, and exploration implications in the Daduhe gold belt are studied. Three categories of gold deposits have been distinguished: “gold deposits in the basement (GDB),” “gold deposits in the cover layer (GDC),” and ...
